Paperless temperature and humidity recorders

November 2003 Analytical Instrumentation & Environmental Monitoring

As an innovative alternative to the portable paper chart recorder, the Selene recorder from PREI Instrumentation records atmospheric humidity and/or temperature in its memory, and also displays the information on an adjustable screen. The duration of the recording can be 12 hours, 24 hours, 7 days or 28 days, and eight recordings will be stored in memory for four weeks before they are over-written. A simple keyboard and graphical instructions makes this unit very easy to use.

Measurements are taken every 15 seconds with an accuracy of 0,5°C and 2% RH. The display can show either the instantaneous numerical value or as a curve with scale values, measurement units, date and time. Previous readings in memory can also be displayed in this form. The entire memory can also be downloaded onto a PC or printer.

Wherever it is necessary to monitor the atmospheric condition, such as in libraries, computer rooms, museums, warehouses, glasshouses, etc, this battery-operated instrument (weighing 1,8 kg) can provide the required secure and reliable information.

At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
